Abstract
The utility model discloses a microwave drying device for lithium iron phosphate. The microwave drying device comprises a frame, a conveyor belt, a microwave drying box and a dehumidification system, wherein a conveyor belt vibration device is arranged below the conveyor belt, the conveyor belt vibration device comprises a motor and a crankshaft driven by the motor, a gas extraction port of the dehumidification system is formed at the top of the microwave drying box, and a hot air system is arranged at the bottom of the microwave drying box. The microwave drying device disclosed by the utility model is a microwave drying device which is specially designed aiming at dry lithium iron phosphate; as the vibration device is arranged below the conveyor belt, the material can jump up and down, and the evaporation of water is further accelerated. Furthermore, the hot air system is arranged at the bottom of the microwave drying box, so that the evaporation of the water can be further accelerated. The microwave drying device disclosed by the utility model has the advantages of simple structure and high drying efficiency.
Description
Technical field
The utility model discloses a kind of microwave dryer, be specifically related to a kind of microwave dryer for LiFePO4.
Background technology
Iron phosphate lithium electrode material is mainly used in various lithium ion batteries.(A is alkali metal from the NTT of Japan in 1996, to disclose first AyMPO4, M is both combinations of CoFe: after the anode material of lithium battery of olivine structural LiFeCOPO4), the Research Groups such as the vertical John. B. Goodenough of university of Texas, USA in 1997, also then reported the characteristic of the lithium of reversibly moving into of LiFePO4, the U.S. and Japan coincidentally deliver olivine structural (LiMPO4), make this material be subject to great attention, and cause research widely and development rapidly.With traditional lithium ion secondary battery anode material, the LiMn2O4 of spinel structure compares with the LiCoO2 of layer structure, and the raw material source of LiMPO4 more extensively, price is cheaper and non-environmental-pollution.
Microwave drying is different from traditional drying mode, and its hot conduction orientation is identical with moisture diffusion direction.Compare with traditional drying mode, have that rate of drying is large, energy-conservation, production efficiency is high, uniform drying, cleaner production, easily realize that automation is controlled and the advantage such as improve the quality of products, thereby more and more come into one's own in dry every field.As far back as the sixties in last century, just the application of microwave drying technology and theory have been carried out to large quantity research abroad, the further development of having got back in nearly decades.The research of China microwave drying technology is started late, and has compared a certain distance abroad, but has also obtained good achievement, also has much research and application achievements.China's microwave drying technology is now for aspects such as food industry, chemical engineering of materials, medical industry, exploitation of mineral resources industry, ceramic industry, lab analysis, wet natural rubber processing.
Now also there is no the special microwave drying equipment designing for dry LiFePO4 specially.
Summary of the invention
The purpose of this utility model is a kind of microwave dryer that is exclusively used in LiFePO4 of design.
The technical solution of the utility model is: a kind of microwave dryer for LiFePO4, comprise frame, conveyer belt, microwave drying oven and dehumidification system, described conveyer belt is arranged with conveyer belt vibrating device, described conveyer belt vibrating device forms by motor with by the bent axle of driven by motor, the bleeding point of described dehumidification system is arranged on the top of microwave drying oven, the bottom of described microwave drying oven is provided with hot-air system, and described hot-air system consists of blower fan and heating wire.
The utility model compared with prior art tool has the following advantages:
The utility model is the microwave dryer designing for dry LiFePO4 specially, because driving-belt is arranged with vibrating device, can make material bob, accelerates moisture evaporation.And be provided with hot-air system in the bottom of microwave drying oven, can accelerate moisture evaporation.The utility model is simple in structure, drying efficiency is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, Reference numeral is: 1-conveyer belt, 2-microwave drying oven, 3-dehumidification system, 4-driving-belt vibrating device, 5-hot-air system.
The specific embodiment
Embodiment
As shown in Figure 1, a kind of microwave dryer for LiFePO4, comprises frame, conveyer belt 1, microwave drying oven 2 and dehumidification system 3.Described conveyer belt 1 is arranged with conveyer belt vibrating device 4, and described conveyer belt vibrating device 4 forms by motor with by the bent axle of driven by motor.Shown in bent axle along the width setting of driving-belt, as required, along the driving-belt direction of motion, many group driving-belt vibrating devices 4 are set.Like this, when bent axle rotates, every rotation one week, will produce the once power on upper top to driving-belt, thereby make driving-belt produce vibration.Material on driving-belt just can be discharged the hot gas of storeroom timely, accelerates dry.
The bleeding point of dehumidification system 3 is arranged on the top of microwave drying oven 2, and the bottom of described microwave drying oven 2 is provided with hot-air system 5, and described hot-air system 5 consists of blower fan and heating wire.As required, along driving-belt 1 direction of motion, upper many group hot-air systems 5 are set, hot blast moves upward, and impels the moisture of material upwards and from dehumidification system 3 to discharge.Play the dry effect of accelerating.
